CELL-CAS E.

SPECIFICATION forming part of Letters Patent No. 606,913, dated July 5,1898.

Application filed July 12, 1897. Serial No. 644,261. (No model.)

.To zr/ZZ whom. t may concern:

Beit known that I, ELIJAH C. Bowne, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofVisconsin, have invented certain new and useful Improvements inCell-Cases; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention relates to certain new and useful improvements in theconstruction of cell-cases such as are used for packing eggs and othersmall articles which it is desirable to keep separate from each otherand it consists in certain peculiarities of construction, as will befully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is a side elevation of one of the strips ofwhich my improved case is composed, showing also in section certain ofthe transverse strips in position. Fig. 2 is a detail perspective viewillustrating the manner in which the crossed strips are held and lockedtogether.

My present invention is an improvement on the device patented to me July21, 1891, and numbered 456,353, and is a simpler and stronger cell-caseand one less liable to break or separate in use than a case constructedin accordance with my said prior patent.

Referring to the drawings, A B represent the strips of which my case isformed. These strips are made of strawboard or other suitable material,and each strip is formed with a series of slots a a in one edge,arranged at equal distances apart, and with other slots b c extendinginward from the opposite edge of the strip, adjacent to the endsthereof. These several slots are preferably formed with parallelstraight walls for a certain distance inward, the strips A being flaredor notched, as shown at CZ cl, at the edges and the said slots startingfrom the narrow part of said flaring notches, and each wall of the slotis continued on a rounded line beyond the line of the said straightportions, as shown by the convex wall e and concave wall f, the wall eterminating in a rounded line forming Ia circular opening marked g inthe series of intermediate slots and h in the end slots, while the wallf terminates in a sharp hook or projection marked c' in the series ofintermediate slots and j in the described end slots,

the bases of said hooks being on the longitudinal central line of thestrip. The intermediate series of circular openings g g are just belowor beyond this longitudinal center of the strip A, measuring from theupper edge, and the circular openings h h near the ends of the strip arejust above said center line, measuring from the lower edge, in theposition of the strip A shown in Fig. l. The

transverse strips B are cut precisely the samel as the strips A, but arereversed in position when the case is put together, as best shown inFig. 2, so that when the strips B are slipped to place the solidportions of said strips beyond the slots will snugly t between thestraight walls of the slots a of the strips A, and the hooks orprojections 'L' of one series of strips will rest within the openings gof the other series, and the bases of the said hooks i i of both serieswill rest rmly against each other at right angles, and the roundedconvex parts e of the slot-walls of the strips of one series will crowdagainst the solid part of the strips of the other series. The outer orend strips or binders are engaged together in precisely the same way,except that the transverse outer strips are entered from the oppositesides of the other strips, thereby making a lock and preventing theaccidental separation of the two series of strips when the cell-case ishandled, as in lifting it from a box or crate.

By this construction I do away entirely with the series of independentperforations shown in my said prior patent, hereinbefore referred to,which proved a source of weak` ness in handling the cell-cases, andobtain just as positive a lock as before.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a cell-case, aseries of strips, each hav ing an intermediateseries of slots extending inward from one edge to a line beyondthelongitudinal center of the strip, one wall of said slot projectinginward and forming a hook with its base at the said center line and saidstrips each having similar slots extending inward from the opposite edgeadjacent to each end to aline beyond said longitudinal center on theother side thereof, substantially as set forth.

IOO

2. The herein-described cell-case, comprising a plurality of strips,each provided with a series of slots in one of its edges and a slot ateach of its ends formed in its opposite edge, each slot extending to apoint just beyond the longitudinal center of the strip and thereterminating in an enlarged aperture,and one wall of each slot extendinginwardly in a rounded convex line beyond the initial straight line ofthe slot-wall, and the other wall of each slot extending outwardly in arounded concave line and thence projecting inwardly, forming a hook orprojection with its base onthe longitudinal central line of said strip,and the said strips being arranged in two series, disposed transverselyto each other, with the hooks or projections of one series in thebaseapertures of the slots of the other series, the bases of the twoseries of hooks or projections being in contact, at right angles to eachother, substantially as set forth. Y

3. In a cell-case, the combination of a plurality of strips, all ofexactly the same construction in all respects, said strips each havingan intermediate series of slots extending inward from one longitudinaledge to a line beyond the longitudinal center of the strip, one wall ofsaid slot projecting inward and forming a hook with its base at the saidcenter line and said strips each having similar slots extending inwardfrom the opposite edge adjacent to each end to a line beyond saidlongitudinal center on the other side thereof, the bases of the hooksformed on the walls of the said last-named end slots also extending onthe longitudinal central line of said strips, in exact line with thebases of the hooks on the walls of the said intermediate series ofslots, substantially as set forth.

4. In a cell-case, the combination of a plurality of strips, all ofexactly the same construction in all respects, said strips each havingan intermediate series of slots extending inward from one longitudinaledge to a line beyond the longitudinal center of the strip, one wall ofsaid slot projecting inward and forming a hook with its base at the saidcenter line and said strips each having similar slots extendinginwardfrom the opposite edge adjacent to each end to a line beyond saidlongitudinal center on the other side thereof, and each slot startingfrom a flaring notch, and with parallel straight edges to both itswalls, and one of said slot-walls thence extending inwardly in a roundedconvex line beyond the initial straight line of the slot-wall, and theother wall of each slot extending outwardly in a rounded concave line,and thence projecting inwardly to form the described hook, said stripsbeing put together, in forming the case, in two series, at right anglesto each other, whereby the solid portions of the strips of one seriesbeyond the slots will snugly iit between the straight walls of the slotsin the strips of the other series, and the said rounded convex parts ofthe slot-walls of the strips of one series will crowd against the solidparts of the strips of the other series, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of lVisconsin, in thepresence of two witnesses.
